Don't forget about the other option I mentioned regarding a straight herbie overflow with two back ups. Would look like this:

I like this option the best. I would leave the second back up drain threaded so that if you wanted to drain the overflow to clean it, you would just un screw the drain pipe and re-open the ball valve to drain it. Would make for nice easy cleaning with the safety of redundancy

Hi FishyFishy

This is the original way I have it, all my bulkheads are slip fitting, the main line in the photo with strainer is with a gate valve, the center is not restricted right to the sump, the far pipe with strainer is the secondary has a ball valve.

I am ordering a T for the durso, that will slip in where the secondary is.

I designed this to be flexable.
